Khushi's colour choices are impeccable . Here's my take.
Green for her parents - Symbolic of safety (green light of the traffic signal). Also signifies fertility and prosperity (crops). One feels the safest with one's parents who are the only ones who are immensely tolerant. Green also is the colour of the heart chakra known as Anahata which enables a person to love more, empathize, and feel compassion. It is another matter that Garima does not often display that selfless love but deep down she does love Khushi and there is no doubt just how fond of Khushi Shashi really is, even if he is not related by blood to her. Prosperity need not be about material wealth alone but prosperity in spirit and that comes from parents only.
Orange for Buaji - Symbolic of caution (orange light of the traffic signal). One has to be cautious around her for she keeps creating hurdles after hurdles for Khushi but she is not altogether bad.
Blue for Payal - Symbolic of water. We already know that this girl has a close association with water whether it is turning on waterworks in her parental home to do the laundry or turning on the waterworks of her eyes every time she gets to hear Mami's choicest curses for her. Lets not forget that 'still waters run deep'. Payal always steps up for Khushi when the going gets tough. Maybe she will do it again if Arnav's brains do not work on their own.
Red for Devi Maiyya (DM) - Going by the traffic signal analogy, it means stop. Right now Khushi is 'katti' with DM and has stopped asking her to help her out. Red is also supposed to be the colour of the root cakra which represents groundedness, trust and a feeling of belonging. Now DM always keeps Khushi grounded and subconsciously Khushi has never lost her trust in her, no matter how much she keeps telling her she does not want her. It is also the colour of love. Khushi's love for DM is all abiding as much DM's love for her.
Yellow for herself - Khushi brings sunshine to the people around her. So what better colour to represent that than yellow. It is also the colour of solar plexus chakra which represents vitality and will. It acts to empower a person and help find his/her personal strength. It will help turn dreams and goals into reality. Khushi is sure to realize her dreams and she will achieve it with her own strength with generous doses of support from DM.
Black for Arnav - Symbolic of darkness - There is no doubt that Arnav is the dark knight in this love story. Black is authoritative and powerful. It can evoke strong emotions and too much can be overwhelming as we are seeing in this track. It also represents a lack of color, the sense of void, emptiness. This guy desperately needs his sunshine (read his Khushi) to fill up the emptiness in his life.
